在CNTK中 - 如何在同一層上使用多個過濾器尺寸(例如過濾器尺寸2,3,4,5)?在CNTK中連接具有不同過濾器尺寸的conv層
繼完成工作here(鏈接到github下面的代碼(1)),我想採取文本,使用嵌入層,應用四種不同大小的過濾器(2,3,4,5),連接結果並將其饋送到完全連接的層。 Network architecture figure
Keras示例代碼:
main_input = Input(shape=(100,)
embedding = Embedding(output_dim=32, input_dim=100, input_length=100, dropout=0)(main_input)
conv1 = getconvmodel(2,256)(embedding)
conv2 = getconvmodel(3,256)(embedding)
conv3 = getconvmodel(4,256)(embedding)
conv4 = getconvmodel(5,256)(embedding)
merged = merge([conv1,conv2,conv3,conv4],mode="concat")
def getconvmodel(filter_length,nb_filter):
model = Sequential()
model.add(Convolution1D(nb_filter=nb_filter,
`enter code here`input_shape=(100,32),
filter_length=filter_length,
border_mode='same',
activation='relu',
subsample_length=1))
model.add(Lambda(sum_1d, output_shape=(nb_filter,)))
#model.add(BatchNormalization(mode=0))
model.add(Dropout(0.5))
return model
